| Overview: | ASPI Digital's MPEG Digital Audio Processor provides high-quality digital-audio compression for mono and stereo signals. It implements the ISO MPEG-1 Audio Compression Algorithm in a single-slot, double VMEbus board. The compression ratio is adjustable over a wide range, delivering sound quality ranging from high-fidelity CD-level down to approximately "toll" telephone quality. For stereo audio-input signals, a joint stereo encoding method is available that exploits similarity between the left and right channels to further compress the signal. The MPEG Digital Audio Processor has both digital-audio and analog-audio inputs and outputs. It can operate at any of the valid MPEG-1 audio sampling rates: 32 kHz, 44.1 kHz, or 48 kHz. A sample rate converter allows digital-audio input at one rate to be encoded at another rate for complete input-rate flexibility. The MPEG Digital Audio Processor has been designed for simple integration into MPEG-1 video encoder systems. UNIX drivers are available. Example code is also available for integration the Digital Audio Processor into other operating environments. |
